The blades are coated with high-hardness, rust-resistant titanium, and the handles are made of PP resin, which is resistant to water, heat, and dish soap. You can wash them thoroughly after use, keeping them clean at all times. In addition, the "thick blade" and the "micro-serrated blade processing" on the blade provide a sharp cutting edge that can firmly cut through not only packaging such as paper packs and food trays, but also slippery and difficult-to-cut ingredients such as seaweed, green onions, kelp, and meat. It is resistant to dirt and rust, and can be washed whole, making it hygienic. The "anti-rattling ring" provides smooth usability and a sharp cutting edge that lasts. ・Titanium coating Length: 174mm Blade length: 65mm Blade thickness: 2.5mm ・Titanium coating Material: Grip = PP, Blade/Crimp pin = Stainless steel, Anti-rattling ring = POM
